# `406` - Not acceptable

## Description

The server cannot generate a response that matches the list of acceptable values sent in the request's `accept` header.

## How to fix

Provide an `accept: application/json` header in the request.

Please note that an exception applies to the  **GET** `/reports/{report_id}` endpoint. You can provide either `accept: application/json` or `accept: application/pdf` there.

## Example
